Imprinting in plants
WitrynaGenomic imprinting refers to an epigenetic phenomenon where the activity of an allele depends on its parental origin. Imprinting at individual genes has only been described in mammals and seed plants. We will discuss the role imprinted genes play in seed development and compare the situation in plants with that in mammals.

Witryna15 lut 2012 · Genomic imprinting is a form of epigenetic inheritance whereby the regulation of a gene or chromosomal region is dependent on the sex of the transmitting parent. During gametogenesis, imprinted regions of DNA are differentially marked in accordance to the sex of the parent, resulting in parent-specific expression. WitrynaGenomic imprinting, the differential expression of an autosomal gene that is dependent on its parent of origin, has independently evolved in flowering plants and mammals. In both of these organism classes, imprinting occurs in embryo-nourishing tissues—the placenta and the endosperm, respectively. It has been proposed that some imprinted …
